A permutation lockis provided to lock the arm 19 in its upper position, in which position of the arm the locking bolts have been moved forward by the-engagement of the segmental gear 17 with pinion16, and the lug 37 is adJacent to the rear face of pinion 16 whereby the looking bolts are locked in looking position. The permutation lock comprises, gener' ally, alatch engaging lug 50, secured with- '15 in theupper groove 25 to the wall 2, apair of spring latches 51' arranged on opposite sides of the outer end of the arm19..ad apt'ed to :engage the lug 50, and a permutation mechanism 52: for" the operation ofeach latch. The lug mechanisms 52' re the same, the following description of one will apply to both.

j The latch isformed with an outer sleeve 66,, reciprocally mounted within the outer end of the arm eand anjnner sleeve 61 turnably mounted with said outer sleeve and reciprocal therewith.v A plunger 62 extends intotheoutward end of the sleeve 61 and has a'reduced end 63 and a shoulder '64, said a reduc'edend fitting within an opening 65 in the end wall ofa cap 66 and said shoul-' der engaging the inner face of said wall. A

spring 68 fitsvvithin the s1eeve;611and bears aga nst the "inner end Wall 6701 said sleeve '1 A: and against the inner endof said. plunger.

A-separablo tumbler center 70 fits onthe outer end of. thelatch sleeve 60 and a similar'ft unibler center 80fits on the outerend. ofth'e sleeve 61. These tumbler centers are formed, with; grooves 71 and 81 to receive lugs 2 I and 82 on; the respective sleeves 60 and "61, whereby said centers are keyed to thefsleeves for relative axial movement.-

80. Thecap 66 fits over the permutation tumblers and its inner end screws on the outer end of the arm 19 against a shoulder 86 on said arm so that the permutationtumblers and the tumbler centers will fit closely 7 but in turning relation between the outer end ofsa'idarm and the inner face of the end wallof'cap 66 The lug72 is adapted to engage the outerjendof the larmf19 to prevent the latch sleeve V v V has two inclinedgcams and two shoulders 56, respectively, ,for,

"The ihner end the latchsleeve has an internal annular flange 87 againstwhich the inner end of the-*latch sleeve 61 abuts and is retained-within thesleeve agalnst "th action of the spring 68. The shoulders 56 are adapted to engage the inner surface off the internal annularsleeve flange 87 and the inner surface ofithe latch sleeve 61 to hold thGfill'll 19' and the look in looking position.

lOand 11 outwardly through; the ope'nings in thelocking'plate on thedoc'r jamh'into 1 and the arm isthenllocked inits upper position by the permutation-lock, thus locking the lock in'locked position; To unlock thel lock the permutation look is first unlocked,

the arm 19 is then swung down, during which operation the gearsegmentll meshes slot 42 thus locking the look in lockedposi- I withwpinion 16 and turns said" pinionwand bolt 14:, the lug 37 is swung out of the-path of said pinion so ,thatthe pinion may vmove inwardly; and the pin 31 "engages theside of slot 30 which withdraws the bolts-14,10

and 11 inwardly untili the ends of the bolts are withdrawn from theopenings inthe lock plate 36 into unlocked position, as shown unlocking position; If it is desired to lock the door from the inside, the latch 40 is disengaged and the arm swung down, during which operation the gear segment 18 meshes with pinion 16 and turns said pinion and bolt 14; the pin 31 engages slot 30 which forces the bolt 14 and bolts 10 and 11 outwardly through openings in the locking plate on the. door jamb, into locking position; thelug 38 passes behind and engages the rear surface of pinion, 16 which prevents backward movement of said bolts; and the latch 40 snaps into engagementwith tion.
